使用VBA文件系统对象，特定的文件扩展名

Question

我使用以下代码列出文件夹及其子文件夹中所有扩展名为xls，xlsx或xlsm的文件。 以下代码有效，但问题是，它列出了子文件夹中所有扩展名的所有文件，但仅列出主文件夹中的 excel 文件。 我无法弄清楚这段代码出了什么问题。 你能帮帮我吗？

Sub List_XL_Files(ByVal SheetName As String, ByVal SourceFolderName As String, ByVal IncludeSubfolders As Boolean)
Dim FSO As Object
Dim SourceFolder As Object
Dim SubFolder As Object
Dim FileItem As Object
Dim lRoMa As Long
Set FSO = CreateObject("Scripting.FileSystemObject")
Set SourceFolder = FSO.GetFolder(SourceFolderName)
lRoMa = ThisWorkbook.Sheets(SheetName).Cells(Rows.Count, 2).End(xlUp).Row + 1
ReDim arrFolders(ctr)
With ThisWorkbook.Sheets(SheetName)
    For Each FileItem In SourceFolder.Files
           strFileExt = FSO.GetExtensionName(FileItem)
           If strFileExt = "xlsm" Or strFileExt = "xlsx" Or strFileExt = "xls" Then
                MsgBox strFileExt
                .Cells(lRoMa + r, 1).Value = lRoMa + r - 7
                .Cells(lRoMa + r, 2).Formula = strFileExt
                .Cells(lRoMa + r, 3).Formula = FileItem.Name
                .Cells(lRoMa + r, 4).Formula = FileItem.Path
                .Cells(lRoMa + r, 5).Value = "-"
                .Cells(lRoMa + r, 6).Value = ""
                .Cells(lRoMa + r, 7).Value = ""
                 r = r + 1                                      ' next row number
                 X = SourceFolder.Path
           End If
    Next FileItem
End With
If IncludeSubfolders Then
    For Each SubFolder In SourceFolder.SubFolders
        ListFilesInFolder SheetName, SubFolder.Path, True
    Next SubFolder
End If
Set FileItem = Nothing
Set SourceFolder = Nothing
Set FSO = Nothing
End sub

谢谢

在For Each SubFolder In SourceFolder.SubFolders后添加以下代码

Call List_XL_Files(SheetName, SubFolder.Path, True)

它会工作
